The Windows posix subsystem is a kludge and an extra dll, and is often 
treated as a poor step-daughter by Microsoft. I strongly suggest we stay 
away from it. Phobos should use the native Windows APIs. I also do not 
want to encourage its use by providing a set of posix declarations for 
Windows as part of Phobos.
